AMUSEMENT DE VICE.

Specification of Letters Patent.

Application filed May 23, 1908.

To all whom it may concern:

Be it known that I, JosnPn DE MARTINO, a subject of the King of Italy,residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Amusement Devices, ofwhich the following is a specification.

My invention relates to improvements in amusement devices of the classin which a series of cars for the conveyance of persons, are adapted torevolve about a central vertical axis.

The invention consists in means for transmitting certain desiredmovements to the cars other than a true circular movement in ahorizontal plane, the principal movement being in a sinuous coursehereinafter shown and described. An undulatory movement and meanstherefor is also set forth.

The invention also consists in means whereby one-half of the number ofcars move in a direction opposite to that of the other half around thecommon vertical axis, a separate sinuous course being provided for eachof the two series of cars.

The invention further consists in an arrangement of the sinuous courseswhereby the cars of one series are adapted to pass between the cars ofthe other series.

The design is novel throughout and each part and its function will beclearly seen from the following description and the accompanyingdrawings.

In the drawings, Figure 1 is a top elevation or plan of my invention,broken away to show a horizontal section taken on the line x of Fig. 4.Fig. 2 is a horizontal section taken on the line y of Fig. 4, Fig. 3 isa transverse section of a radial I-beam and portions connectedtherewith, Fig. 4 is a central vertical section showing parts brokenaway for clearness of illustration, Fig. 5 is a detail view, Fig. 6 is adetail view taken at right angles to that of Fig. 5, Fig. 7 is also adetail view, Fig. 8 is a transverse section taken on line 2 of Fig. 7,and Fig. 9 is a transverse section taken on line it of Fig. 7.

In the drawings, the same letters and numerals refer to like parts.

In the drawings, 1 represents a central stationary pillar rigidlysecured to a flanged tubular socket 2 by means of bolts 3. Connectedwith flanges in the socket 2 by means of the bolts 4, is a circular base5 comprising the radial I-beams 6 and the segmental portions 7 arrangedbetween the I-beams 6 and securely connected therewith by means ofthebolts 9 and the screws 10. The bolts 9 and the screws 10 are designedto secure permanently and rigidly the I-beams 6 with the segmentalportions 7, the bolts 11, however, are removable in order that thedevice may be taken apart and readily reassembled. L shaped rim portions12 are secured to the segmental portions 7 by means of the bolts 13, therim portions 12 thus forming a substantial edge to the base 5. Thecircular parts 14, 15, 16 and 17 have a construction similar to that ofthe base 5, the part 16 being shown in detail in Figs. 2 and 3.

The roof portion 17 is securely bolted to a flanged collar 18 whichcollar, is secured to the pillar 1 by means of the screws 19. Braces 20are designed to add rigidity to the roof 20 and have rigid connectionwith the lugs 21 and 22 by means of the pins 23. Lugs 22 are formed inthe ring 24 being integral therewith, the ring 24 being attached to thepillar 1 by means of the screws 25. The lugs 21 are attached to the roof17 by means of the bolts 26. The periphery or rim portion of the roof 17is supported by vertically disposed members 27, which are equally spacedand rigidly secured to the roof 17 and to the base 5. The members 27 areprovided with slots or perforations 28 to receive braces 29, whichbraces are adapted to eonnect rigidly with the roof 17 and the members27 to add rigidity to the structure.

Depending from the roof 17 and connected therewith by means of the bolts30, is an endless I-beam 31 forming a double track as shown by dottedlines in Fig. 1 and in detail in Fig. 5. The sinuous course of the track31, is similar to the track 32 provided in the device. The track 32 issecurely fixed to the base 5 by means of bolts 33, its axis beingidentical with that of the track 31, but having a relative arrangementas shown in Fig. 1.

The circular part 16 is provided with a split, central hub 34, havinglugs 35 and removable bolts 36. The hub 34 is journaled to the ring 37,which ring is secured firmly to the pillar 1, by means of screws 38. Inthe part 16 are slots 39 radially disposed and provided with T-rails 40,as shown in detail in Fig. 6. The circular part 14 has a constructionsimilar to that of part 16 excepting the rails 41 which are flat bars asshown in detail in Figs. 7 and 9.

Rigidly secured to the pillar 1 by means of bolts 42, is a circular part15 adapted to sup port a motor 43, which is secured to the member 15 bymeans of bolts 44. The armature 45 of the motor 43 is provided with adriving bevel gear 46 adapted to drive bevel gears 47 and 48. The drivengear 47 is rigidly fixed to the shaft 49, which shaft is journaled inbearings 50, 51 and 52, and provided with a driving gear 53. Thebearings 50, 51 and 52, are at the extremities of arms 54, 55 and 56respectively, which arms are provided with integral split rings forrigid engagement with the pillar l.

The driven gear 57 is fixed to the shaft 58 which is journaled inbearings 59 and 60, and provided with a driving gear 61. The bear ing 60is rigidly secured in the part 15, and the bearing 59 is at theextremity of an arm 62 provided with an integral split ring for engagement with the pillar 1.

The driven gears 63 and 64 are bolted rigidly to parts 14 and 16respectively. The gears 63 and 64 are split diametrically and areprovided with lugs 65 and removable bolts (not shown). The ring 67 isrigidly secured to the pillar 1 by means of screws 68. Secured in thering 67 are arms 66, which arms extend outward radially and connect withvertically disposed members 69. The

members 69 are equally spaced and are rigidly secured in the rim portionof the part 15. Braces 70 add rigidity to the structure and extend fromlugs 71 in the ring 37 to the arms 66, to which they are rigidlyconnected by pins 72.

Cars 73 are suspended by hangers 7 5, which hangers are square in crosssection, and are'provided with forks 76 at their upper extremities.Secured in forks 76 are pins 77, to which are j ournaled rollers 78,which rollers are adapted to run in eccentric paths or grooves 79,provided in the rollers 80. The grooves 79 thus cause the hangers andthe cars 73 to have a slight vertically reciprocating movement during arevolution of the rollers 80. Tubular shafts 81 are provided with forksat their upper extremities to which are journaled rollers 80 whichengage the tracks in the I-beam 31. The interior of each shaft 81 isformed to receive the square hangers 75, the hangers 75 being adapted toreciprocate in the shaft 81.

A carriage A comprising transverse members 82 and rollers j ournaled tothe members 82 is adapted to be free to rotate on the shaft 81. Themembers 82 are connected by bolts 83, and the carriage A held inposition on the shaft 81 by means of the collar 84 pinned to the shaft81.

Supports 84 for the cars 74 are square in cross section, and areprovided with forks at their lower extremities in which are secured pins85. J ournaled to the pins 85 are rollers 86, which are adapted totravel in eccentric paths or grooves 87 in the rollers 88. Tubularshafts 89 are provided with forks at their lower extremities in whichthe rollers 87 are journaled. The interior of each shaft 89 is formed toreceive the square shafts 84, as shown in detail in Fig. 8, the shafts84 being adapted to reciprocate in shafts 89. A shoulder 90 is providedon shaft 89 to support a carriage B. Carriage B is similar inconstruction to carriage A, and is adapted to be free to rotate on theshaft 89. Simultaneously with the movement of the hangers 75 along thetrack 31, the carriages A move radially in the slots 39 and rotateslightly on the shafts 81. The carriages B are adapted to move in radialslots provided in the part 14 in a manner similar to the movement ofcarriages in slots 39. The cars 73 and 74 are adapted to follow theirrespective sinuous courses in opposite directions, and to pass eachother as shown in Fig. 1.

The construction as set forth is preferred, but it is obvious thatmodifications may be incorporated in the device without limiting thescope of my invention. For instance, the number of turns in the sinuouscourses may be greater or less.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:
